摘要：2005年对上海市闸北区空气中PM10（空气动力学当量直径〈10μm的可吸入颗粒物）的污染状况进行了1年的连续监测。结果表明：全年各月PM10污染均以2级为主。占总样本数的67．6％；其次是1级占20．0％，3级占11．0％，劣于3级占1．4％。全年空气质量状况9月份最好，11月份最差。PM10浓度与C0、NO2浓度呈显著相关性，说明机动车尾气是该区域PM10的主要来源；PM10污染程度还明显地受到降水，气温、气压、风向、风速．相对湿度等气象条件以及北方沙尘暴的外部输送的影响。
The ambient air pollution of inhalable particulates （PM10）, which aerodynamic equivalent diameter is below 10 μm, was monitored continuously in Zhabei District of Shanghai in 2005. Results indicated that in the whole year 67.6% of the samples were at the level of Class 2 of PM10 while 20.0% were at Class 1, 11.0% at Class 3 and the rest 1.4% were inferior. Of the whole year, the quality of the ambient air in September was found the best while the worst in November. PM10 content showed a strong correlation with the contents of CO and NO2 indicating that the motor vehicle exhaust might be of its predominant sources. It has also been revealed that PM10 pollution was obviously associated with various meteorological conditions such as precipitation, atmospheric temperature, air pressure, wind direction, wind speed and relative humidity, as well as the intrusion of dust storm from the northern China.
